Key Transparency aims to secure the distribution of public keys for end-to-end encrypted (E2EE) messaging systems, such as Whatsapp. It achieves this by building a verifiable append-only data structure called a Log, similar to Certificate Transparency.
Cloudflare verifies Key Transparency Logs to ensure the transparency of end-to-end encrypted messaging public keys. This component is called an Auditor. Cloudflare provides an API for anyone to monitor the work of the Auditor, and verify the state of its associated Logs locally. This local validation can be done with cloudflare/plexi cli for instance.
